Orchid Identification Quiz #1

In 2006 the electronic version of the Journal of the Native Orchid Society of South Australia Volume 30 No 2 March contained a quiz – Do you Know Your Leaves? It featured photographs of the leaves of 15 different orchid. In 2011 Robert Lawrence produced a book titled Start With the Leaves which was based upon the premise that the flower is not always present but identification is still possible.

Many but not all can be identified to species level by the leaf alone.

So here is a web version (with some variations) of the original quiz – how well do you know your leaves?

Hint – 20 of them are South Australian, more specifically, the Mount Lofty Ranges region.  One is a weed.

Arachnorchis tentaculata
Thelymitra benthamiana
Thelymitra antennifera
Pyrorchis nigricans
Plumatochilus sp Woodland Bearded Greenhood
Orthoceras strictum
